more especially to the so-called drawing miiil'lolurnaccs. As known in such furnaces the articles are subjected to :1- high heat and iu'rnngi-uwnts must be n'ovidod for putting in or introducing i-lzre articlos to be burned in ELSPDA'JOOI room and disc nnn therefrom, which shows red. hoot. The do n L1\' l'1g for such introduction and discharge. oi the orticlis aim, as usual, arranged within the burning chamber and. undergo therefore a'qniclc destruction due to this high heat. This defect of the furnace it! 6L as hitherto in use shall be removed by my invention, which permits of :1 continuous heating of the articles to be burned by fitting tho iurnace with 1-. feeding arrangements, mrrzmgfi outside of th' 'i'is.-ating chamber mid adapted to roroczttod vertically and horizontally. By this Way the loading doviccs are expose- 1 to the high host for a, short time only and continuous feeding o: the articles is maintained Without tho tending devices being liable to injury by host.

To make my invention more clear, I refer to the ac com )anying drawing, in which:

It may be pointed out that the proper structure of the trucks can be changed and adapted to the special requirements prevailing in the working of the furnace. Modifications'in this direction can be provided without departing from the feature of my invention. The arms 0 and i if required can be fitted with an inner cooling byusing a tube-like jib and introducing water therein. Also the feeding truck can be modified.

Of course the track I: may consist of two mils. An essential advantage is furthermore obtained by heating the burning chamber from beneath, offering no disturbances in heating and gentle feeding of the articles. Such a heating chamber is also able to be heated directly.

Having thus fully described the nature of this involition, what I desire to secure by Letters Patent 0;" the United States is: i
